Great support

I was really grateful that I was told to wash this bra before I wore it, because it truly made a HUGE difference in how it fit. When it arrived, it was super small... but after washing it, it's do-able. I say do-able because honestly --and ideally-- I need a bigger cup size and a smaller band size. I ordered a 6+ since I'm a 30H or I. I am definitely overflowing the cups, and the band is on it's tightest hooks, but this is as close to comfort in a sports bra that I've come. I love not having an underwire! But Knix, PLEASE PLEASE PLEASE come out with a 6++ and 6+++. And please make offer a smaller band size. There is absolutely NO ONE offering comfortable bras for women with small band size (30") and large cups sizes. What I would give to have a comfortable no-underwire bra!

Stretched Out Too Soon

At first I LOVED this bra. It held the ladies well and didn't chafe anywhere...plus no underwires! I started out on the second loosest hook and it fit great. Woo hoo!!

Then within a few months it had stretched quite a bit so I had to tighten it one level. A few months later and I had to tighten it again. It's now on the smallest band hook and frankly I could do even tighter. I haven't changed size/weight during this time so the bra has stretched. It's still wearable, just not as comfortable.
